Features

• #11019 Allow model, enum, union, and scalar declarations to be used as expressions. A declaration used in expression position has its corresponding type marked with expression: true and is not registered in the enclosing namespace. It may be named or anonymous (in which case it has no name).

  This is an experimental feature that must be opted into by adding declaration-expressions to the features list in tspconfig.yaml; using a declaration expression without it reports a declaration-expression-disabled error.

  They can be used anywhere an expression is expected, including aliases, model properties, decorator arguments, template arguments, function/call arguments, and tuples.

  model, scalar, and union declaration expressions support the same extends clause as their statement form (union extends additionally requires the union-extends feature).

  alias Foo = enum {
    a,
    b,
  };
  model Bar {
  status: enum { active, inactive };
  unit: scalar extends string;
  inner: model Inner { x: string };
  }
  @​Versioning.versioned(enum Versions { v1, v2 })
  namespace MyService;

• #11019 Allow decorators to be applied to model, enum, union, and scalar declarations used in expression position. Inline decorators can be applied directly, and augment decorators (@@) can target them through a navigation reference (such as ::type).

  model Foo {
    status: @doc("the current status") enum { active, inactive };
    inner: @doc("nested model") model Inner { x: string };
  }
  @@​doc(Foo.status::type, "the current status");

• #11019 Allow a doc comment to be applied inline to a model, enum, union, or scalar declaration expression, just like an inline @doc decorator.

  model Foo {
    status: /** the current status */ enum { active, inactive };
  }

• #11019 Improve formatting of declaration expressions (model, enum, union, and scalar used in expression position) that carry doc comments and/or decorators. When the inline form would exceed the print width, the doc comments and decorators are now each placed on their own line and the whole block is indented one level instead of overflowing.

  model Foo {
